![### Question 12:
**Problem Statement:**
If 3 moles of Sodium Phosphate react, how many moles of Sodium Hydroxide will form?
**Chemical Equation:**
\[\_\_\_\_\_ \text{Na}_3\text{PO}_4 + \_\_\_\_\_ \text{KOH} \rightarrow \_\_\_\_\_ \text{NaOH} + \_\_\_\_\_ \text{K}_3\text{PO}_4\]
**Options:**
a) 1
b) 3
c) 6
d) 9
**Solution Explanation:**
To answer this question, one needs to balance the chemical equation for the reaction and use stoichiometric relationships.
First, balance the chemical equation:
1. Write out the unbalanced equation:
\[\text{Na}_3\text{PO}_4 + \text{KOH} \rightarrow \text{NaOH} + \text{K}_3\text{PO}_4\]
2. Balance the number of each type of atom:
\[\text{Na}_3\text{PO}_4 + 3\text{KOH} \rightarrow 3\text{NaOH} + \text{K}_3\text{PO}_4\]
Now, use the balanced equation to determine the moles of Sodium Hydroxide (NaOH) produced when 3 moles of Sodium Phosphate (Na_3PO_4) react.
From the balanced equation, 1 mole of \(\text{Na}_3\text{PO}_4\) produces 3 moles of \(\text{NaOH}\).
Therefore, if 3 moles of \(\text{Na}_3\text{PO}_4\) react:
\[ 3 \text{ moles Na}_3\text{PO}_4 \times \frac{3 \text{ moles NaOH}}{1 \text{ mole Na}_3\text{PO}_4} = 9 \text{ moles NaOH} \]
**Correct Answer:**
d) 9](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ffd56fc4e-1883-49db-9ee4-a33c0e94306f%2Fabcafa4b-0dbd-4eb2-909e-74e44233a553%2Fwdgkqned_processed.jpeg&w=3840&q=75)
